BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a computer peripheral power saving system, and more particularly to a power saving control device for detecting a power source of a computer peripheral device when the computer enters an idle mode. & [Prior Art]

In today's fast-changing times of technology, computer and computer peripherals have become an indispensable part of modern life. Among them, computers and side devices include scanners, printers, fax machines, and multifunction machines. However, the computer peripheral devices currently used typically consume more than 1 watt of power in a standby mode, and even the power rectifier itself must consume more than 1 watt of power. As a result, computer peripheral devices not only cause unnecessary waste of energy, but also generate electromagnetic waves harmful to the human body, causing so-called electromagnetic interference (EMI) problems.

In recent years, the development of power-saving technologies for computer peripheral devices has gradually sprouted. For example, in the power saving device and method for computer peripheral devices disclosed in the Patent Publication No. 5〇2154 of the Republic of China, the computer screen determines whether the computer screen enters the power saving mode by the power saving command issued by the computer host on the computer screen. Or the startup mode, and the power-saving command issued by the host computer is the horizontal and vertical synchronization signal sent by the host computer to the computer screen. However, not all computer peripherals can continuously receive power-saving commands from computers like computer screens. Take a scanner or a transaction machine as an example, it will be called by the computer when it is needed. In addition, the current computer peripherals themselves
